Cannot initialize the LTDVDBurnerClass without installing the SDK

I am working with c# windows forms app and cannot the initialize the LTDVDBurnerClass on a non-development machine unless I install the LeadTools SDK.

When I call the LTDVDBurnerClass's constructor, I get the following error:

Retrieving the COM class factory for component with CLSID {E2B7DE10-38C5-11D5-91F6-00104BDB8FF9} failed due to the following error: 80004005

I included the redistributable files in the install program (DSKernel2.dll and LTMM15.DLL), and I am registering the Lead dll's in the system folder. Also, I checked dependency on LTDVDBRN2.dll (and all the other dll's in the package) for missing files, but everything seems to be in place. The target platform is set to x86.

What am I missing?

The help file should explain which redistributables you need in the article "Multimedia Files You must Include With Your Application (Redistributables)".  Additionally you can test and see which DLLs are being loaded by your application at any time by using Process Explorer.  This is a free program that is available from http://www.microsoft.com/technet/sysinternals/utilities/ProcessExplorer.mspx.  Use this program and see what DLLs load on your development machine and then see what is missing from your deployment machine.

Make sure that you are also registering all of the filters, codecs, and COM objects you are deploying.

Process Explorer was a good tip, but didn't have the granularity I needed. I ended up using filemon.exe instead. It not only tells you what is missing, but where the application thinks the file should be located. I was able to run it on both machines and compare the logs. Very tedious, but it got the job done.

Thanks,
